Group 1 - The Yellow River has achieved continuous flow for 26 years since 1999, providing significant support for the economic and social development of the basin [2] - In the 2024-2025 period, the Yellow River's main stream supplied over 22.3 billion cubic meters of water, aiding ecological protection and high-quality development in the region [2] - Due to extreme weather conditions, some provinces in the Yellow River basin experienced droughts, prompting the Yellow River Water Resources Commission to ensure water supply safety and food security [2] Group 2 - The use of nano-materials in irrigation channels has improved water delivery efficiency by 27% in the Liuyuan Kou irrigation area [3] - Modernization efforts in the People's Victory Canal irrigation area have increased the water utilization coefficient from 0.536 to 0.609, reducing the irrigation cycle by an average of 8 days [3] - Research indicates that timely irrigation significantly enhances the enzyme activity in wheat leaves, leading to higher grain weight [3] Group 3 - Irrigation from the Yellow River has notably contributed to summer grain yield, with timely watering resulting in a grain weight of 0.0924 pounds, surpassing that of dry land by 0.0186 pounds [4] - The integration of water and fertilizer technology in the Lankao demonstration area has resulted in wheat protein content nearing 15%, meeting high-quality standards [4] - Effective water management from the Yellow River plays a crucial role in ensuring water supply safety, supporting economic growth, and improving the ecological environment [4]

Core Viewpoint - The Yellow River has achieved continuous flow for 26 years since 1999, supported by effective water resource management and allocation strategies, despite facing drought conditions in certain regions [1][2]. Group 1: Water Resource Management - The Yellow River Water Resources Commission has implemented the "Four Waters and Four Determinations" principle to enhance water resource conservation and efficient utilization, successfully completing annual water allocation tasks [1]. - In the 2024-2025 period, over 22.3 billion cubic meters of water were supplied from the Yellow River to the basin and related areas, supporting ecological protection and high-quality development [1]. Group 2: Drought Response and Ecological Support - The Yellow River basin experienced varying degrees of drought in the summer of 2024 and spring-summer of 2025, leading to significant water demand for drought relief [1]. - The commission proactively planned and deployed resources to ensure water supply safety, food security, and ecological safety in drought-affected provinces [1]. - Cross-basin water replenishment efforts included 0.08 billion cubic meters of emergency water supply to the South Four Lakes, effectively alleviating local drought conditions [2]. Group 3: Ecological Restoration Efforts - Cumulative ecological water replenishment efforts included 3.74 billion cubic meters to the Uliangsuhai and 1.72 billion cubic meters to the estuarine delta, improving local water ecological environments [2]. - The commission is actively promoting the restoration of the Qinhai and Heihe rivers as part of ongoing ecological recovery initiatives [2].

Core Viewpoint - The Yellow River has achieved continuous flow for 26 years since 1999, supported by unified water regulation, which is crucial for ecological protection and high-quality development in the Yellow River basin [1] Group 1: Water Management - The real-time flow measured at the Lijin Hydrological Station on August 12 was 588 cubic meters per second, indicating effective water management practices [1] - The cumulative water supply from the Yellow River for the 2024-2025 period is expected to exceed 22.3 billion cubic meters, contributing to the ecological balance [1] Group 2: Ecological and Economic Impact - The Yellow River has supported the water supply for the Grand Canal for four consecutive years, enhancing ecological protection efforts [1] - The ongoing water management initiatives are vital for ensuring sustainable development in the Yellow River basin [1]
